How to Install the ISONAS IP-Enabled Reader-controller 27
2.2.8: LOCK WIRING -- 2 READERS TO 1 LOCK
If you are wiring both sides of the door to control IN and OUT access, then you will
have the special condition of wiring 2 Reader-Controllers to a single locking
mechanism.
If there is not a door sensor switch connected to the door, then typically you connect
both reader-controllers to the door’s lock circuit.
For Fail-Secure locks, wire the two reader-controller’s lock circuits in-parallel
(Lock is connected to both reader-controller’s Tan leads)
For Fail-Safe locks, wire the two reader-controller’s lock-circuits in-series
(Gray lead of Reader #1 connects to Pink lead of Reader #2, Gray lead of
Reader #2 connects to lock).
If there is a door sensor switch connected to the door, then Reader #1 controls the
door, and is wired to the door’s Door-sense switch. Use the following steps to cause
Reader #2 to activate the REX button on Reader #1.
Two Readers & One Lock Wiring
Steps: See Figure 14

from reader #2 to the Green

black (ground) lead on reader
